Re: Random Vertical Lines on Samsung LCD TV

Unless this turns out to be an unrepairable panel, I will repair it and document what I did and share my findings. Recycling is OK but I like reusing/repurposing so much more. Plus this is going to be my guinea pig project on electronic repair. Had been a software guy most of my life. It's time to really work on the fun stuff. I'll Keep you guys posted on my Adventure with this TV. I'm sure I'll have questions along the way as I dig through the anals of circuit analysis. From what I've seen on this forum, there is not a shortage of experts...

Re: Random Vertical Lines on Samsung LCD TV

Now, I understand the "shimming" quick fix for some issues with lcd lines. However if the problem is due to an intermittent connection, I would suspect that it would always be the same lines that are affected. Thanks for the susggestion though. I still like the fix suggested on one of the youtube videos. THe guy used a bat and tapped on top of the tv until the lines disappeard. If I had to do that, I would take a bat and take a full swing right in the middle of the panel.

Re: Random Vertical Lines on Samsung LCD TV

OK.. Thanks. So if the vertical lines changes location depending on what is being displayed, then the problem is likely upstream and most likely to be one of the logic boards (TCON, Mainboard) and not the Panel/TCP/Driver IC assembly. This is a great forum. So many helpfull people.

Re: Random Vertical Lines on Samsung LCD TV

Thanks PlainBill. I'll try opening this unit up and see. It's already broke, what is the worse that can happen other than electricute myself. I promise not to do that. I was suspecting it to be not the panel since the lines follow the overlayed OSD type display. The adventure begins. Thanks again.

Hi,

I'm new to these forums. I have a problem with my Samsung LCD TV. There appears vertical lines where ever there is text on the screen. See my picture attachced. I asked a local TV repairman and he said I have to replace the whole pane. Could this be fixed by replacing some kind of printed circuit board that drives the lcd panel? Thanks for all the help in advance....
